Automobile windshield molding

ABSTRACT

A windshield molding is installed in the space between a windshield and a periphery of a window opening of a vehicle body panel. The windshield molding comprises a pair of extruded side molding parts, a pair of extruded corner molding parts, and an extruded upper molding part integral with and extending between the side and corner molding parts. Each of side molding parts associated with each side edge of the windshield is larger in thickness compared to the upper and corner molding parts, having a water drain channel which extends in and along such large-thickness part.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to an automobile windshield molding for a motor vehicle body so as to seal the space between a windshield and a periphery of a window opening of a vehicle body panel.

2. Description of the Related Art

An automobile windshield molding is usually attached around an edge of a windshield so as to seal the space between a windshield and a window opening of a vehicle body panel. The automobile windshield molding is directly attached to the vehicle body panel or is supported by a fastener fixedly mounted on the body panel.

Examples of such molding are exemplified in Japanese Patent Laid-Open Publication No. 244820/1989 and No. 269612/1989.

In the former, an extruded molding has two grooves on its side surfaces. One of the two grooves is removed at a portion associated with the upper part of the windshield. At corner portions, the molding is elastically reshaped so that the glass receiving groove on the upper part and that on the side part can be aligned. The other groove on the molding at each side panel part serves as a water drain channel.

Since the cross section of this molding is uniform, the molding cannot be applied to a vehicle body panel having a slanted portion for the windshield. In addition, the ends of the removed groove may be exposed at the corner portions.

To overcome the above inconveniences, Japanese Patent Laid-Open Publication No. 269612/1989 was proposed, in which a long extruded molding is of a simple shape and has a connecting portion. The connecting portion is cut at the upper and side molding parts so that the connecting portion extends to different heights at these molding parts. A glass receiving groove is formed when cutting the connecting portion. Then the molding is elastically reshaped so that the glass receiving groove at the upper molding part and that at the side molding part can be aligned. At the side molding part, the connecting portion serves as a wall, outside of which a water drain channel is formed.

In the second case, there are some inconveniences. For example, a part of the molding should extend over the glass surface to a certain amount when considering variations in manufacturing precision or assembling work. In such a case, the more the molding extends over the glass surface, the less the sectional area of the water drain channel.

SUMMARY OF THE INVENTION

It is therefore an object of this invention to provide an automobile windshield molding, in which a water drain channel is formed along the vehicle body side panel so as to serve as a dam.

According to a first aspect of this invention, there is provided an automobile windshield molding for sealing the space between a windshield and a periphery of a window opening of a vehicle body panel. The molding comprises a pair of extruded side molding parts, a pair of corner molding parts, and an upper extruded molding part integral with and extending between the side and corner molding parts.

Each of the side, corner and upper molding parts includes an exterior wing adapted to cover a space, on the exterior side of the vehicle, between the window-opening periphery of the vehicle body panel and each of side, corner and upper edges of the windshield. The majority of the inward wing portion associated with each of the side edge of the windshield is larger in thickness compared to the inward wing portion associated with the upper edge of the windshield. Such inward wing portion has a water drain channel which extends in and along such large-thickness part and opens inwardly of the window opening. The exterior wing has a connecting portion extending from an interior side of each of the exterior wing through the space between the window-opening periphery of the vehicle body panel and each of the edge of the windshield and terminating in a foot and a lip on the interior side of the vehicle body panel.

According to a second aspect, the interior side of the exterior wing is divided into inward and outward surfaces by the connecting portion. There is a varying difference in height between the inward and outward surfaces. The large-thickness part of each side inward wing portion has a thickness varying commensurate with the height difference of the inward and outward surfaces.

According to a third aspect, the interior side of the exterior wing is divided into inward and outward surfaces by the connecting portion. The inward and outward surfaces are aligned in height with each other. The large-thickness part of each side inward wing portion bulges exteriorly of the vehicle.

According to a fourth aspect, the water drain channel has a rectangular cross section.

According to a fifth aspect, the water drain channel varies in width of the opening and depth commensurate with the thickness of each of the side exterior wing and has a triangular cross section.

DETAILED DESCRIPTION Embodiment 1

An automobile windshield molding according to one embodiment of the invention is shown in FIGS. 1 to 6.

As shown in FIG. 1, a molding 2 is installed so as to seal the space between a windshield and a periphery of a window opening of a vehicle body panel.

The molding 2 is a long strip in the shape of T, and an upper molding part 2A to be mounted between the upper edge of the windshield and the roof panel 12, side molding parts 2C between side edges of the windshield 11 and pillar panels 13 of the vehicle body, and corner molding parts 2B for connecting the upper and side molding parts 2A and 2B. All of these molding parts 2A to 2C are extruded as one unit.

Each of the side, corner and upper molding parts 2A to 2C comprises an exterior wing 21 adapted to cover a space, on the exterior side of the vehicle, between the window-opening periphery of the vehicle body panel and each of side, corner and upper edges of the windshield. The exterior wing 21 includes an inward wing portion 21a for covering the peripheral edge of the windshield, an outward wing portion 21b for covering the periphery of the vehicle body panel, and a connecting portion 22 extending from an interior side of the exterior wing 21.

The outward wing portion 21b has a uniform thickness in its lengthwise direction. On the contrary, the inward wing portion 21a is uniformly thick on the upper molding part 2A, but is thickened gradually from the corner molding part 2B to the side molding part 2C. Specifically, the inward wing portion 21a is thickest at the central portion of the side molding part 2C. Then the inward wing portion 21a is made gradually thin toward the end of the side molding part 2C.

The connecting portion 22 divides the interior side of the exterior wing into inward and outward surfaces. There is a varying difference in height between the inward and outward surfaces. The connecting portion 22 is short on the upper molding part 2A (shown in FIG. 3), and gradually becomes longer on the side molding parts 2C (shown in FIGS. 4 to 6), because the distance between the surface of the windshield 11 and the surface of the front pillars 13 is increased compared with the distance between the surface of the windshield 11 and the surface of the roof panel. Specifically, the connecting portion 22 is made gradually longer from the corner molding part 2B toward the central portion of the side molding part 2C, and is again made a little shorter at the end of the side molding part 2C.

The connecting portion 22 has a foot 24 extending inwardly along the end thereof as shown in FIG. 2. The foot 24 serves to assist in supporting the windshield 11. The connecting portion 22 also has a flexible lip 25 which extends outwardly along the end thereof.

A thin metallic foil 23 serving as a core metal is embedded lengthwise in the connecting portion 22 near the junction with the exterior wing 21.

A water drain channel each 28 is defined on an inner wall of the large-thickness part of the inward wing portion 21a of each side molding part 2C. The water drain channel 28 has a triangular cross section and is gradually deepened as the inward wing portion 21a becomes thick. An upper wall 212a and a lower wall 211a of the water drain channel 28 are made equally thick by adjusting the depth of the water drain channel 28. The drain channel 28 is located on the inward wing portion 21a between the end 2D of the corner molding part 2B and the end of the side molding part 2C.

The upper surface of the foot 24 and the interior side of the inward wing portion 21a are aligned in height with each other throughout all of the molding parts. In other words, the distance between the foot 24 and the inward wing portion 21a is equal to the thickness of the windshield 11.

The molding 2 will be attached to the windshield 11 and the vehicle body as described below.

FIGS. 3 to 6 show the manner in which the molding 2 is attached between the corner and the side edges of the windshield 11.

A window opening of the roof panel 12 has a slanted wall 12a and a flange 12b for receiving the windshield 11. The front pillar 13 also has a slanted wall 13a and the flange 13b for receiving the windshield 11. The slanted wall 13a has a height increased gradually from the corner to the side of the vehicle body panel compared with the slanted wall 12a.

Firstly, the molding 2 is attached around the peripheral edge of the windshield 11. Between the upper and corner parts, the edge of the windshield 11 is sandwiched between the foot 24 and the interior side of the inward wing portion 21a. Each of the side edges of the windshield 11 is sandwiched between the foot 24 and the interior side of the wall 211a.

A dam rubber 14 in strip shape is applied around the edges of the flanges 12b and 13b. An adhesive 15 is applied to the outer edge of the dam rubber 14. Then the windshield 11 having the molding 2 mounted therearound is placed on the dam rubber 14. The windshield 11 is then pressed toward the vehicle body, so that the outward wing portion 21b of the molding 2 overlies the body panels 12, 13. Therefore, the foot 24 of the molding 2 is fastened by the adhesive 15, and the flexible lip 25 of the molding 2 is flexibly contacted to the slanted walls 12a, 13b, thereby fastening the windshield 11 to the body panel.

The difference of the height between the outer surface of the body panel and the windshield 11 is equal to the difference of height between the slanted walls 12a and 13a as shown in FIGS. 3 to 6. As shown in FIG. 3, the upper edge of the windshield 11 is nearly flush with the surface of the roof panel 12. The height difference H₁ is small between the windshield 11 and the corner part of the front pillar 13 (shown in FIG. 4), while the difference H₂ is large at the side edges of the windshield 11 (shown in FIG. 5). The difference H₃ between the end of the side molding part and the front pillar 13 is larger than H₁ but smaller than H₂ (shown in FIG. 6).

It is understood that the thickness of the inward wing portion 21a of the molding 2 is changed according to the varying difference of the height between the windshield 11 and the body panel.

The edge of the outward wing portion 21b of the molding 2 is in close contact with the roof panel 12 between the upper and corner parts of the windshield 11. From the upper to corner molding parts, the inward wing portion 21a slightly extends toward the outer surface of the windshield 11, i.e. as shown in FIG. 4, the inward wing portion 21a is slightly thickened at the corner molding parts compared with the upper molding part. Therefore water is guided on the surface of the windshield along the wall of the inward wing portion 21a.

Since the inward wing portion 21a is slightly thickened at the corner molding parts, the exterior wing 21 is free from wrinkles even if it is bent along the corner portions.

FIG. 5 is a cross sectional view of the molding taken along the line III--III of FIG. 3. As shown in FIG. 5, the water drain channel 28 is deepest and widest at the central portion of the side molding part 2C. The edge of the windshield 11 is sandwiched between the foot 24 and the interior side of the wall 211a of the inward wing portion 21a. The outward wing portion 21b is in close contact with the outer surface of the front pillar 13. On the side central portion of the windshield 11, water is guided downwardly along the drain channel 28 which has a largest opening.

FIG. 6 is a cross sectional view of the molding taken along the line IV--IV of FIG. 3. The difference of the height between the body panel and the windshield is smaller than that at the side central portion. The drain channel 28 is lessened in its depth and width at the end portion compared with that at the side central portion. The outward wing portion 21b is contact with the outer surface of the front pillar 13 so that the windshield 11 is sandwiched between the foot 24 and the interior side of the lower wall 211a of the inward wing portion 21a. At the end portion of the molding 2, water is guided downwardly on the windshield along the water drain channel 28. Since the thicknesses of the upper wall 212a and the lower wall 211a are uniform on the side molding part 2C, it will be not unnatural even when the size of the water drain channel 28 changes.

A molding device for producing the molding 2 will be described with reference to FIGS. 7 and 8.

A molding device 3 comprises dies having openings for extruding a plastic material. A first die 31 has an opening 34 which is shaped according to the cross sectional shape of the molding 2. The opening 34 has portions 341 and 343 corresponding to the shape of the exterior wing of the molding 2. The molding material is extruded through the opening 34.

A second die 32 is a rectangular plate having an opening 35 which is shaped according to the cross sectional shape of the connecting portion 22 of the molding 2. The opening 35 has portions corresponding to the foot 24 and the flexible lip 25. The second die 32 is placed on the first die 31.

When the second die 32 is placed on the first die 31, both of the openings 34 and 35 are in the cross sectional shape of the upper molding part 2A. Opposite ends of the second die 32 are guided by a guide 32a so that the second die 32 is slidable longitudinally in the opening 35. The second die 32 is connected via an operation lever 32d to a converter 32b which is driven by a motor 32c so as to convert the rotary motion to the rectilinear motion.

A third die 33 slides perpendicularly of the sliding direction of the second die 32, being located above the first die 31. The third die 33 is a thin rectangular plate having a tip 331 pointed with an acute angle. The third die 33 is guided by die guides 33a on opposite sides thereof so as to be movable toward the opening 34 of the first die 31. The third die 33 is connected via an operation lever 33d to a converter 33b which is driven by a motor 33c so as to convert the rotary motion to the rectilinear motion. The position of the third die 33 above the first die 31 is determined so that the third die 33 projects to a predetermined portion in the opening 34. In other words, the third die 33 projects into the opening 34 so that the water drain channel 28 is formed on the side molding 2C.

In operation, the molding machine 3 produces the molding 2 as described hereinafter.

The molding 2 comprises a side molding part 2C, a corner molding part 2B, upper molding part 2A, a corner molding part 2B and a side molding part 2C formed in the named order in succession.

Each of the side molding 2C and corner molding 2B will be described referring to FIG. 8.

Firstly, the second die 32 is placed on the first die 31 so that the openings 34 and 35 of the first and second dies are in the cross sectional shape of the side molding 2C. The plastic material is extruded through the openings 34 and 35 together with a metallic foil strip which is inserted in the upper central portion of the opening 35.

Then the motor 32c is driven to operate the converter 32b. The converter 32b makes, via the lever 32d, the second die 32 slide in the direction indicated by an arrow X so as to widen the opening 35 (to lengthen the connecting portion). Then the opening 35 is widened at the portion 343 so as to increase the thickeness of the inward wing portion 21a of the molding 2. The opening 34 is kept as it is at the portion 341 thereof by a shield 342 regardless of the movement of the second die 33. The portion 341 of the opening 34 corresponds to the outward wing portion 21b of the molding 2.

The motor 33c is driven in synchronization with the rotation speed of the motor 32c so as to operate the third die 33. The rotary motion of the motor 33c is converted into the rectilinear motion by the converter 33b so that the third die 33 slides perpendicularly of the second die 32, i.e. in the direction indicated by an arrow W. Then the third die 33 projects into the portion 343 of the opening 35, pushing, with the pointed tip 331, the extruded molding so as to form the inward wing portion. Under this condition, the extruded molding is shaped so that the inward wing portion 21a is thickened gradually to form the water drain channel 28 thereon.

When the molding is extruded to a predetermined length, the motors 32c and 33c are rotated reversely so as to move the second die 32 in the direction indicated by an arrow Y. In synchronization with the motor 32c, the third die 33 is retracted in the direction indicated by an arrow V so that the opening 35 is lessened gradually to shorten the connecting portion of the molding. Therefore the extruded molding serves as the side molding part 2C having the inward wing portion 21a and the drain channel 28 which are decreased in thickness at the end of the corner molding part 2C. Since the third die 33 is retracted in the direction V in synchronization with the moving speed of the second die 32, the depth and the width of the opening of the drain channel 28 change but the thicknesses of the upper wall 212a and the lower wall 211a remain the same in the extruded molding.

When the third die 33 is retracted completely from the portion 343 of the opening 35, the second die 32 is moved in the direction Y until the top of the opening 35 of the second die 32 is flush with the top of the shield 342 of the first die 31. Under this condition, the molding extruded from the openings 34 and 35 is shaped so that the inward wing portion 21a is thinned gradually so as to serve as the corner molding part 2C.

The top of the shield 342 of the first die 31 and the top of the opening 35 of the second die 32 are flush with each other, i.e. the shape of the openings 34 and 35 matched together corresponds to the cross sectional shape of the upper molding part 2A. Under this condition, the motors are stopped, and the plastic material is extruded through the openings 34 and 35 for a predetermined period of time to produce the upper molding part 2A.

When the upper molding part 2A becomes long as predetermined, the motor 32c is driven again to produce the corner molding part 2C. Thus the molding 2 is produced in the shape of a strip.

Embodiment 2

A second embodiment of the invention will be described referring to FIGS. 9 to 12.

FIG. 9 is a cross sectional view showing a windshield molding 4 attached in the space between the vehicle body penal and the windshield, taken along the line I--I of FIG. 1. The same reference numerals as those in the first embodiment will be assigned to the portions and units which are identical to those in the first embodiment, and the description on them will be omitted.

The molding 4 comprises a pair of extruded side molding parts 4C, a pair of extruded corner molding parts 4B, and an extruded upper molding part 4A integral and extending between the side and corner molding parts.

Each of the molding parts 4A, 4B and 4C includes an exterior wing 41 and a connecting portion 42.

The exterior wing 41 has an inward wing portion 41a and an outward wing portion 41b.

The connecting portion 42 has a foot 44 extending inwardly along the lower end thereof. The foot 44 has a dent 444 at its end. A flexible lip 45 extends outwardly along the lower end of the connecting portion 42. A wire 43 serving as a core material is embedded along the joint between the connecting portion 42 and the exterior wing 41 of the molding 4.

A metallic decorative film 49 is embedded along the central portion of the exterior wing 41 of the molding 4, i.e. along the border between the inward wing portion 41a and the outward wing portion 41b. The outward wing portion 41b has a uniform thickness throughout the molding 4.

The thickness of the inward wing portion 41a of the molding 4 is changed according to the varying difference of height between the body panels 12, 13 and the windshield. The depth and width of a water drain channel 48 are varied with the thickness of the inward wing portion 41a. In addition, an upper wall 412a and a lower wall 411a are uniformly thick throughout the side molding part 4C, respectively.

The windshield 11 will be installed on the vehicle body by using the molding 4 as described below.

FIG. 10 is a cross sectional view of the molding 4 taken along the line V--V of FIG. 9. At the upper and corner molding parts, the interior edge of the windshield 11 is supported on the dent 444 of the foot 44. The inward wing portion 41a covers the exterior edge of the windshield 11 41a. The outward wing portion 41b is in close contact with and covers the corner part of the front pillar 13. The flexible lip 45 is contacted to a slanted wall 13a of the front pillar 13.

The water on the windshield 11 is guided along the thickened wall 411 of the inward wing portion 41a.

FIG. 11 is a cross sectional view taken along the line VI--VI of FIG. 9. At the end of the corner molding part, a water drain channel 48 is narrower and shallower than that at the central portion of the side molding part 4C. At the end of the corner portion, water is guided in the drain channel 48 along the lower wall 411a.

FIG. 12 is a cross sectional view, taken along the line VII--VII of FIG. 9, at the central portion of the side molding part 4C. At the central portion of the side molding part 4C, the drain channel 48 is widened and deepened on the lower wall 411a. The water is guided through the enlarged drain channel 48.

Embodiment 3

FIG. 13 shows a third embodiment of the invention. As shown in FIG. 13, a molding 5 comprises a pair of extruded side molding parts 5C, a pair of extruded corner molding parts 5B, and an extruded upper molding part 5A integral with and extending between the side and corner molding parts.

Each of the molding parts 5A, 5B and 5C includes an exterior wind 52 and a connecting portion 51. The exterior wing 52 has an inward wing portion 57 and an outward wing portion 58. The thickness Ta of the inward wing portion 57 (shown in FIG. 14) and the thickness Tb of the inward wing portion 55 (shown in FIG. 15) vary with the difference of height of the windshield 11 and the body panels 12, 13. The connecting portion 51 of the molding parts 5A, 5B and 5C is inserted into the space between the windshield 11 and the body panels 12 and 13 so as to cover the space decoratively.

As shown in FIGS. 13 and 14, the connecting portion 51 of the side molding part 5C includes a lip 55 extending inwardly along the lower end thereof, and a panel lip 56 extending outwardly along the central portion thereof.

A water drain channel 59 having a rectangular cross section is formed on the interior side of the inward wing portion 57 of the molding 5. The side molding part 5C is attached to the side edge of the windshield 11 by means of the interior side of the exterior wing 52 and the lip 55. A fastener 62 is stuck to the slanted walls 12a, 13a of the body panels 12, 13 with a double adhesive tape 61. A projection 56a of the panel lip 56 engages with a projection of the fastener 62, so that the outward wing portion 58 engages with the body panel flexibly.

As shown in FIGS. 13 and 15, the thickness Tb of the inward wing portion 57 is small at the upper molding part 5A compared with that at the side molding part 5C. The structure of the upper molding part 5A is substantially the same as that of the side molding 5C except for the inward wing portion 57, which does not have any large-thickness part.

As shown in FIG. 13, thickness and width of the inward wing portion 57 are gradually increased from the corner molding part 5B toward the side molding part 5C. The drain channel 59 formed on the large-thickness part of the inward wing portion 57 gradually becomes shallower from the side molding part 5C toward the corner molding part 5B and disappears finally.

The molding 5 is first attached around the edge of the windshield 11, and is then mounted in the window opening of the vehicle body. Otherwise, the windshield 11 is attached in the window opening beforehand, and then the molding 5 is inserted in the space between the windshield 11 and the body panels 12, 13 with the connecting portion 51 sandwiched in the space.

The molding 5 includes a reinforcing core material 54 embedded therein, and a decorative tape stuck on the inward wing portion 57. In FIGS. 13 to 15, reference numeral 66 stands for a sealant for fastening the windshield 11 and the molding 5 to the vehicle body panels 12, 13, and 67 represents a dam rubber for preventing flow of the sealant 66.

The water pushed by a non-illustrated wiper toward the opposite sides of the windshield is guided along the drain channel 59 formed on the large-thickness portion of the inward wing portion 57. Therefore the water is prevented from dispersing onto the side windows of the vehicle, thereby keeping a good field of view from the driver's position.

Embodiment 4

FIG. 16 is a partial cross sectional view showing a corner molding part 7B of a molding 7. The molding 7 comprises a pair of extruded side molding parts 7C, a pair of extruded corner molding parts 7B, and an extruded upper molding part 7A integral and extending between the side and corner molding parts. Each of the side, corner and upper molding parts includes an exterior wing and a connecting portion 76.

The exterior wing has an outward wing portion 75 for covering the periphery of the vehicle body panel, and an inward wing portion 77 for covering the edge of the windshield. The outward wing portion 77 and the inward wing portion 75 are equally thick at the upper molding part 7A. However the inward wing portion 75 changes its shape gradually. Specifically, the inward wing portion 75 bulges to extend exteriorly at each of side molding parts 7C. As shown in FIG. 20, the inward wing portion 75 bulges exteriorly as if it rotates at a radius OP. The edge of the inward wing portion 75 is contoured as shown by P, P₁, P₂, P₃, P₄ in FIG. 20.

A water drain channel 78 is formed on the large-thickness portion of the inward wind portion 75 at the side molding part 7C.

The shape of the connecting portion 76 is substantially the same at the molding parts 7A, 7C. The connecting portion 76 has a lip 79 extending inwardly along the lower end thereof, and a panel lip 71 extending outwardly along the lower end thereof.

When the molding 7 is inserted into the space between the window opening and the windshield 11, the windshield 11 is sandwiched by the interior side of the exterior wing and the lip 79 of the connecting portion 76, so that the windshield 11 is mounted to the vehicle body via the molding 7. Under this condition, the panel lip 71 is flexibly contacted to the slanted portions 12a, 13a of the roof panel 12 and the pillar panel 13, and the outward wing portion 77 is flexibly contacted to the roof panel 12 and the pillar panel 13.

In FIG. 16 to FIG. 19, reference numeral 82 stands for a reinforcement core material embedded in the connecting portion 76, and 83 represents a dam rubber for preventing flow of the sealant 73.

A molding machine for producing the molding 7 will be described with reference to FIG. 21 to FIG. 23.

The molding machine comprises a basic die 102 having an opening 101, a first movable die 104 which rotates centrally of a fulcrum 103 so as to change the area of the opening 101 to form the inward wing portion 75, and a second movable die 105 which advances and retracts into and from the opening 102 so as to form the water drain channel 78 on the inner wall portion of the side molding part 7C only.

The first movable die 104 is in the shape of sector, being positioned over the opening 101 for forming the inward wing portion 75, and being rotatable centrally of the fulcrum 103. The first movable die 104 is operated by a non-illustrated motor which is located behind the basic die 102.

The second movable die 105 is guided by a pair of guides 106 so as to be rectilinearly movable. The rotary motion of a motor 107 is converted into the rectilinear motion by a converter 108. Therefore the second movable die 105 moves rectilinearly, advancing and retracting into and from the opening 101 of the basic die 102.

As shown in FIG. 21, the first movable die 104 is at one of its predetermined positions, minimizing the area of the opening 101 for forming the exterior wing of the molding. The second movable die 105 remains away from the opening 101. Under this condition, the upper molding part 7A is produced. The first movable die 104 is moved gradually, and the second movable die 105 is also advanced gradually into the opening 101. Then the thickness of the inward wing portion 75 is increased gradually. At the same time, the drain channel 78 is deepened and widened gradually on the inward wing portion 75. Thus the corner molding part 7B will be formed as shown in FIG. 22.

When the first movable die 104 reaches the other predetermined position, and when the second movable die 105 reaches its destination in the opening 101, production of the side molding part 7C will be started.

The foregoing operations of the first and second movable dies are repeated to extrude the upper, corner and side molding parts 7A to 7C in the integral form.

When the second movable die 105 has a sharply pointed tip, the water drain channel 78 will be also formed on the relatively thin corner molding part 7B.

FIG. 24 to FIG. 26 show a further molding according to a further embodiment of the invention. Only the portions different from those of the molding 7 will be described hereinafter.

A molding 110 is attached to the roof panel 12 and pillar panels 13 by means of a fastener 112 stuck by an adhesive 111. Specifically, a dent 114 at the lower end of the connecting portion 113 engages with the fastener 113 so as to make the inward wing portion 115 contacted with the surface of the windshield 11. Then the molding 110 is attached around the edge of the windshield 11. Under this condition, the outward wing portion 117 of the molding 110 is in flexible contact with the body panels 12, 13 via the lip 112a of the fastener 112.

It is needless to say the moldings according to the invention are applicable to installation of a rear window.
